YD series pole-changing multi-speed three-phase asynchronous motor is developed based on the Y series of new change pole speed three-phase asynchronous motor, with high efficiency, large starting torque, low noise, small vibration, etc. Due to this series of machine can change the speed of the motor by changing the pole, so as to achieve the rational matching power and variable speed system is simplified, thus in the textile, printing and dyeing, chemical industry and other industries widely used. YD series pole-changing multi-speed three-phase asynchronous motor in the protection grade, use conditions, structure and installation dimensions and Y series is exactly the same. Their level of power the corresponding relationship between the size of the installation of comparable to similar foreign products, thus has good compatibility with advanced products at home and abroad, to facilitate exports and spare motor for imported equipment. YD series pole-changing multi-speed three-phase asynchronous motor rated voltage of 380 v, rated frequency 50 hz, protective class is IP44, cooling method for IC411, USES the class B insulation, the structure and installation of the series motor type, size and shape of the ya series motor is the same. YD series two-speed motor is single winding, three speed motor for the double winding. It is to use the change of the stator winding connection to change the number of motor, so that the motor in a set or two sets of winding for two or more speed. This series of motor products fully meet the ya D series (1 p44) change pole speed three-phase asynchronous motor more technical conditions ", as the series motor has to speed the transformation of the nature of the load requirements and grading, so as to achieve the rational matching power and simplify the characteristics of variable speed system. Is suitable for the need of cascade speed regulation drive mechanism, mainly used in universal, combination, special cutting machine tools and mining, metallurgy, textile, printing and dyeing, chemical industry, agricultural machinery, etc. Note: because the space is limited, motor power, the number of revolutions, current, cannot release, parameters such as specific consultation please call
